With the development of front and rear separation and separation as the development standard of the Internet industry, programs have also begun to develop toward APIs. APIs have become the key to program development and maintenance.
API is an important part of the application. With the iteration of application updates, the API is constantly updated. Among them, the process from the beginning of the design to the abandonment of the API is called the life cycle of the API, and the role of the API management platform is to help the enterprise manage the entire process of the API life cycle.
How the API management platform manages the API life cycle
To understand how the API management platform manages the API life cycle, you need to know the process of the API life cycle. The complete API life cycle process is shown in the figure below, which can be summarized as: 1. API design and development 2. API testing 3. API launch And maintenance 
1. API design and development In the API design phase, the person in charge needs to define the API and define the functions, parameters and other information of the API.
After the design is completed, it enters into the iterative plan. Back-end developers refer to the API documentation to start development, and front-end personnel can use the API management platform to quickly generate MockAPI for front-end development. 
2. API testing After API development is completed, the tester will test the API, write test cases, and design application scenarios for testing with reference to the API documentation.
3. API online and maintenance After confirming that the API can operate normally and is online, it is another start of API management. It is necessary to check the API regularly to understand the stability of the API and monitor whether each API is healthy, so as to quickly locate the wrong API.
The API gateway can also be used when the project reaches a certain scale. 
The above briefly introduces several important stages of the API life cycle, and uses Eolinker to demonstrate. The API life cycle involves many points. If you plan to manage the API, you need to consider all aspects of the API and choose an API management platform. It is conducive to faster and more efficient management of API life cycle.
